Re: Nickel Covers vs. Exposed Coils
I think there's certain times when the nickel covers enhance your tone, depending on the gutiar you're looking to put them on. The PRS/Les Pauls come to mind the most, and you're normally hearing covered pickups on the majority of 'em anyway.
I've had Pearly Gates and '59's under covers on Pauls and they work awesome. Simple fix if you're wondering? A/B 'em. Play 'em with and without covers to learn what you like.
